IMPROVEMENT IN SPINNING-MAGEINE.

Be it known that we, JAMES E. HOOPER, of Woodberry, in the county ofaltimore, and State of Maryland, and BENJAMIN ARNOLD, of East Greenwich, in the county of Kent, and State of Rhode Island, have invented certain new and useful Improvements in Machines for Spinning and Twisting Cotton, Wool, and other Textile Materials; and we' do hereby declare that the following is a full and correct description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

' In all the figures the same letters arc used to `ir-idicate similar parts.

Figure 1 is a perspective .view of a partei' a front of'a spinning-frame.

Figure 2 is a vertical cross-section ofthe same.

Figure 3 is an enlarged front view of the attachment for holding and putting on the empty bobbins.

Figure 4 is a vertical longitudinal section ofthe ring-rail. l I

Figure A5 is an enlargedrview of a part ofthe ring-rail.4

Figure 6 isa top view of tig. 3.

Our improvements consist of alterations and additions to a spinning or twisting-i`rarne, for the purpose ot' removing the bobbins of yarn when full, and supplying their places by empty bobbins, a process usually called doiiingn The construction and operation are as follows:

On the inside ot' the ring-rai1 a, (see g. 4,) is placed the bar o, suspended to the rail by tl1e=links e e, so that, when moved endways, it will be raised into the position shown byA dotted lines in fig. 4 bringing the projections 's e up under the bobbin-heads-in the rings'.

On the outside of the ring-rail a, (seo iig. 5,) are the devices for separating the thread into two parts. t is a stationary cutter or catch, and d is the moving one. These cutters or catchesare made with sharp edges or notches, which catch the yarn, as the bobhin falls oil' in front, and cut or separate it, so as to leave an end of the yarn to windaround the empty bobhin. The yarn may also be separated by rubbing it between two surfaces, (see y, g. 5,) the yarn being caught between two parts, which slide oneuupon the other, whereby the twist is taken out on one side, and the yarn is separated with the least pull. I

A sliding bar, g, is fastened on `the top or back of the ring-rail a, (see iig. 5,) having projections on one side, to` stop the traveller on' the ring, when on the backa or behind the spindle, so that, when the bobbins fall o in front, the en d of yarn may lie across the flange that held the bobbin. The bar is slid endways, to bring the projections againstthe ring, so as to stop the traveller. This bar may be hinged to the back of the rail a, so as to turn up against the ring and accomplish the same object. v i

A rail or bar, 7c, (see figs. 3 and 6,) having springs, b E, to hold the empty bobbinsc, is placed behind the spindles, and supported on the arms Z l, (see'ig. 3,) which are pivoted at one end to the bar, and at the other to the slotted knees :t x, so as tobe movable in two ways, one up and down, and the other swinging in and out on the arms` e z are knee-levers7 one end of which is fastened to the slotted knees@ zu, and the other ends are connected v together by a` rod,p, so Vthat they may allmove alike.

Th whole of this apparatus, for holding and putting on the empty b obbin, is supported by the curtain A., o r by standards from the under side of the frame D, by pins in the slotted knees 2: as, and pivots in the angles of the knee-levers e e.V y i The operation is as follows:

When the bobbins areready to be doed, the machine is stopped, when the ring-rail is at the lowest part of its motion, and the bar g, tig. 5, is drawn a little endways,iuntil the projections'on it touch the rings, when 'alittle backward motion is given to the driving-cylinder to bring the-travellers againstthe projections; then,

by drawing the bar o, iig. '4, endways, until the projections upon it come up under theuheads of the bobbins, and

by pressing on the lever r, (which is fastened to the lifting-apparatus of the ral,),with the foot, the ring-rail a will be raised, and with it all the bobbins on the spindles B, until they are high enough to fall oil', which they will do in front, if the projections on bar o are under the back edge of the bobbin-heads, and draw the yarn across the rings from the traveller, which was stopped at the back of the lring; and the yarn will also lie between the two pieces, t d, one of which, el, being slid endways, the yarn will be separated.

Now, by moving the lower end of lever v to the left, the bar j) will move the knee-levers e e; and raise the slotted knees x'zr. When these reach thelirnit of their motion, the end of lever v will move the rail c, swinging it out on its arms, so as to bring the Aempty bobbins c on it-over the tops of the'spindles B, when, b'y reversing the motion of the levers v, the whole will first be moved down, so as to bring the bobbins'on to the spindles, and then the rail c will be swung back, leavingr the bobbins on the spindles, and also ou the end of the yarn which lies across the ring, so thatvupon starting the machine, the yarn will be wound around the bobbins c c.

When the"full bcbbins fall from the spindles, they are caught in ya box or trough suitably placed for that purpose, and the device for parting the yarn may be put on the edge of this trough, or on a bar between the trough and ring-rail a, if preferred; and the bar, with projections for stopping the travellers, may be placed jon a separate bar back of the'ring-rail.'

Theseseparate motions may be more or less connected together, so as to leave but few primary motions, or the whole of them may be .connected in various ways, so as to be produced at regular intervals by the same power that drives the machine, making it an automatic dotfein Having thus described our invention, whatwe claim, and desire to secure by Letters Patent, is-

1. The combination ofthe bar o, or its mechanical equivalent, with the ring-rail, for the purpose of throwing off the empty bobbins, substantially as herein set forth. v

' 2. The combination, with a spinning-machine, substantially as described, of the notched bar and sliding thread-separator. v y

3.. The rail la', and the mechanismfor operating it, all constructed substantially as described, and for the purpose set forth.

BENJAMIN ARNOLD.
